[LDM #GUQ-669331]: Both Radar and Satellite feeds stopped downloading abruptly

John,

We suspect that your campus network is throttling the connections between
our LDM and yours. Over the years, we've determined that the signature of
such throttling is that products in a a low-volume feed arrive with little
or no latency while those in a high-volume feed arrive with high latency.
Consequently, we re-configured the LDM on Mammatus to also request
IDS|DDPLUS from iddb.unidata.ucar.edu in order to verify this hypothesis.
The latency plots

and
    
http://rtstats.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?IDS|DDPLUS+mammatus.ttu.edu
are initially consistent with throttling. We'll need to let it run through
another 18Z slowdown, however, in order to be certain.


Regards,
Steve Emmerson
